Single Virtual IP, single pool, 2 members

Hello friends.

I have configured Reverse proxy that single pool with the two pool members is behind the single Virtual Server.

VIP:10.200.17.10:443 -------->Pool1: Members: 10.200.5.10:7007 AND 10.200.5.10:7005

There are diverse domain name for each service.

10.200.5.10:7007 ----> cg.company.local and

10.200.5.10:7005 sg.company.local

irules configuration is below:

when HTTP_REQUEST {

 if { [string tolower [HTTP::host]] eq "cg.company.local" and [HTTP::path] ne "/SVFE2/" and [HTTP::path] eq "/" } {

   HTTP::respond 302 Location "https://[HTTP::host]/SVFE2/"

 }

 elseif { [string tolower [HTTP::host]] eq "sg.company.local" and [HTTP::path] ne "/sv/" and [HTTP::path] eq "/" } {

   HTTP::respond 302 Location "https://[HTTP::host]/sv/"

 }

}

But I encounter with the errors. Sometimes sites don`t not open.

I deem it is related to load balancing behavior of F5.

Could you give me a hand to find a solution?

    Hi,

    can you try this:

    when HTTP_REQUEST {
if { [string tolower [HTTP::host]] == "cg.company.local" && [HTTP::uri] == "/" } {
	HTTP::redirect "https://[HTTP::host]/SVFE2/"
}
elseif { [string tolower [HTTP::host]] == "sg.company.local" && [HTTP::uri] == "/" } {
	HTTP::redirect "https://[HTTP::host]/sv/"
}
}

    Regards

    I tried this, but did not work.

    The first cg.company.local works, but sometimes it gets errors, I suppose it redirect to 7005 instead of 7007 service port. Second one did not work at all.

    I did with node, but this time redirection did not work.

    when HTTP_REQUEST {

     if { [string tolower [HTTP::host]] starts_with "cg.company.local"} {

        node "10.200.5.14:7007"

         }

       elseif { [string tolower [HTTP::host]] starts_with "sg.company.local" } {

       node "10.200.5.14:7005"

     }

     }

    If I write full link https://[HTTP::host]/SVFE2/ , it works.

    But when I write only cg.company.local, it does not as it is not forwarded.

    I fixed problem.

    when HTTP_REQUEST {

     if { [string tolower [HTTP::host]] eq "cg.company.local" and [HTTP::path] ne "/SVFE2/" and [HTTP::path] eq "/" } {

       HTTP::respond 301 Location "https://cg.company.local/SVFE2/"

       node "10.200.5.14:7007"

         }

      elseif { [string tolower [HTTP::host]] eq "sg.company.local" and [HTTP::path] ne "/sv/" and [HTTP::path] eq "/" } {

       HTTP::respond 301 Location "https://sg.company.local/sv/"

       node "10.200.5.14:7005"

     }

     }

      Hi,

      "Node command" works if uri equals "/", for your rule.

      Use this iRule if you want to redirect all hostname based requests to node.

      when HTTP_REQUEST {
	if { [string tolower [HTTP::host]] equals "cg.company.local" } {
		if { [HTTP::uri] equals "/" } { 
			HTTP::respond 301 Location "https://[HTTP::host]/SVFE2/"
		}
		node "10.200.5.14:7007"
	}
	elseif { [string tolower [HTTP::host]] equals "sg.company.local" } {
		if { [HTTP::uri] equals "/" } { 
			HTTP::respond 301 Location "https://[HTTP::host]/sv/"
		}
		node "10.200.5.14:7005"
	}
}
